Evaluation of Watershed Characteristics Effects on Stream Flow (A Case of Chacha Watershed, Abay Basin, Ethiopia)

Watershed characteristics of this study includes, land use or land cover, slope, and climate factors are an important factor that affects the streamflow in River basin. The objective of this study was to evaluate the effect of watershed characteristics on stream flow in Chacha watershed of Abay basin. In this study, the streamflow in the Chacha watershed was simulated using the semi-distributed hydrologic model, Soil and Water Assessment Tool (SWAT). The sensitive parameters analysis, SWAT output calibration, and validation for streamflow in the watershed were done using SWAT-CUP (SUFI-2-algorithm). The streamflow was calibrated, and results from calibration show acceptable range (0.88 for R2 and 0.82 for NSE) between observed and simulated stream flow respectively. The results of validation were also acceptable range (0.87 for R2 and 0.81 for NSE). In this study land use and land cover changes, climatic characteristics (rainfall and temperature variation), and slope variation of the topography were having an impact on the streamflow of the Chacha watershed. However, the land use and land cover impact have a more significant influence on the streamflow than other factors. This was due to the stream flow during 2018-LULC was increased by 6.8% over the 1998-LULC. This was the larger percent of increase over the other two factors in the study area. So, to reduce the streamflow in the study area model base land use mitigation measures was done for three basic scenarios by increasing the forest and decreasing the agricultural land with 5%, 10% and 15%. The result shows decreasing annual stream flow by 5.51%, 11.86% and 24.3% for each increment of forest land from the baseline respectively.
